Working Principle

The SI5338G-B01866-GM is a programmable clock generator that delivers precision clock signals as outputs. The fundamental working principle behind the clock generator is an oscillator circuit, which provides a reference signal (usually a quartz crystal oscillator). This reference signal is used to control a voltage-controlled oscillator (VCO), which produces the clock signals as outputs. The control input to the VCO is provided by a set of internally programmable parameters and the CLKIN input. The parameters can be populated or adjusted using the SPI interface.

The SI5338G-B01866-GM clock generator provides eight outputs, which can be configured to provide programmable duty cycles and spread-spectrum modulation. The duty cycle of each output is programmable, allowing for very accurate control of the duty cycle. The integrated spread-spectrum features (SSM) allow the frequency of the outputs to be adjusted in order to reduce radiated emissions from the clock signals. This allows designers to meet the Part 15 FCC regulations for emissions.

The SI5338G-B01866-GM supports frequency hopping and dynamic frequency control, which enable the clock generator to adjust the output frequency based on input conditions. This feature allows the clock generator to quickly react to changes in the external environment and provides excellent timing accuracy.

The SI5338G-B01866-GM offers a low jitter performance of 0.12ps, with a total jitter budget of 0.25ps. The integrated spread spectrum capabilities allow the clock signals to conform to the Part 15 FCC regulations. The device also has integrated power-down modes, allowing the clock generator to be shut down when not in use.
